application Great Britain July 14, 1952 3 Claims. (Cl. 196-24) Claims priority,

This invention relates to a process for reducing the content of vanadium and/or sodium in petroleum and petroleum products.

In the complete specification of the co-pending application Ser. No. 1,029/51 there was described a process in which the content of vanadium and/or leum or bauxite in the presence dium are/is deposited on the contact material.

The contact material preferably contains from 140% by weight of TiOz the remainder consisting essentially of alumina.

The preferred ranges of operating conditions for the process are as follows:

Space velocity v./v./hr 0.5 to 2.0

Temperature F. 750 to 800 Pressure p. s. i. ga 500 to 1,500 Hydrogen recycle rate S. C. F./B l,000 to 10,000

An example of the application of the invention to the treatment of a petroleum residue will now be given.

Example Sodium and vanadium removal from Kuwait 53% volume residue.

Conditions employed:

Feedstock Kuwait 53% vol. residue. Space velocity 1.0 v./v./l1r. Temperature 780 F. (416 C.) Pressure 1000 p. s. i. ga.

Hydrogen recycle rate 4000 S. C. F./B. Direction of flow Upward. Duration of test 50 hours.

Results obtained: Titania on alumina (4.70 wt. TiOz).

2. A process according to claim 1, wherein the contact material contains from 1-10% by weight of TiOz, the remainder consisting essentially of alumina.

3. A process according to claim 1, wherein the treated feedstock is subsequently passed to a hydrogenation zone for the removal of organically combined sulphur.
